FIG 1. Case 2.
A, Right vertebral angiogram on day 1, anterolateral view, shows no abnormal findings.
B, Follow-up right vertebral angiogram on day 7 shows a dissecting aneurysm in the vertebral artery, distal to the PICA origin.
C, Right vertebral angiogram immediately after embolization of the dissection site.
D, Follow-up MR angiogram 7 months after embolization.

FIG 2. Case 5.
A, Right vertebral artery angiogram, anterolateral view, shows a dissecting aneurysm distal to the PICA origin.
B, Right vertebral angiogram, anterolateral view, immediately after coil embolization of the dissection site.
C, Left vertebral angiogram, anterolateral view, shows an increase in diameter relative to that before embolization.
D, Follow-up right vertebral angiogram, anterolateral view, 1 month after embolization shows complete occlusion of the affected site and preservation of the PICA.

FIG 3. Case 13.
A–E, Initial right (A) and left (B) vertebral angiograms on day 0 show bilateral vertebral artery dissection. Angiograms on day 2 show marked dilatation of the left vertebral artery dissecting aneurysm before (C) and after (D) coil embolization. Follow-up right vertebral angiogram on day 10 (E) shows progressive dissection.
